Claim 1
Independent Claim
219 words
THE METHOD OF CONVERTING HYDROCARBONS IN THE PRESENCE OF A FIXED BED OF COMMINUTED SOLID CONTACT MATERIAL COMPRISING: INTRODUCING REACTANT HYDROCARBONS INTO ONE SIDE OF A BED OF CONTACT MATERIAL, AT A PRESSURE WHICH IS HIGH ENOUGH TO FORCE THE HYDROCARBONS TO PENETRATE THE BED, STOPPING THE FLOW OF REACTANT HYDROCARBONS TO THE BED PRIOR TO THE EMERGENCE OF REACTANTS FROM THE OTHER SIDE OF THE BED AND STARTING THE FLOW OF COMBUSTION SUPPORTING GAS INTO SAID OTHER SIDE OF THE BED, AT A PRESSURE WHICH IS HIGH ENOUGH TO FORCE THE COMBUSTION SUPPORTING GAS TO PENETRATE THE BED AND DRIVE THE REACTANTS BACK OUT OF THE BED, WITHDRAWING THE CONVERSION PRODUCT DRIVEN FROM THE BED TO A COLLECTION ZONE, STOPPING THE FLOW OF COMBUSTION SUPPORTING GAS JUST PRIOR TO THE EMERGENCE OF SAID GAS FROM THE FIRST SIDE OF THE BED AND STARTING THE FLOW OF REACTANTS INTO SAID FIRST SIDE OF THE BED, AT A PRESSURE WHICH IS HIGH ENOUGH TO FORCE THE REACTANTS TO PENETRATE THE BED AND DRIVE THE COMBUSTION GAS BACK OUT OF THE BED, WITHDRAWING THE COMBUSTION GAS DRIVEN FROM THE BED TO A RECEIVING ZONE AND MAINTAINING THE PULSATION OF GASES IN THE BED SUFFICIENTLY SHORT TO PROVIDE A SUBSTANTIALLY CONTINUOUS FLOW OF REACTANTS TO SAID COLLECTION ZONE OF SUBSTANTIALLY UNIFORM COMPOSITION.
